[GPI] connector
➀
Confirm that the status between [POWER MONITOR
HOT] (24pin) and [POWER MONITOR COLD] (25pin)
is ON.
Under the test conditions.
Example circuit
➁
Short circuit [INPUT 1] (No.3 pin) and GND, confirm
that the status between [OUTPUT 1] (No. 14 pin)
and GND becomes ON.
Open circuit [INPUT 1] (No.3 pin) and GND, confirm
that the status between [OUTPUT 1] (No. 14 pin)
and GND becomes OFF.
➂
Test [INPUT 2] to [INPUT 8] in the same manner.
Example circuit
4
[SIGNAL/PEAK] indicator of MONO
INPUT 1 to 6
• Confirm that the [SIGNAL/PEAK] indicator of
corresponding channel lights RED.
•
•
All [PAD] switches: OFF
Input the 1 kHz, -40 dBu sine wave
to the channel to be checked.
5
[SIGNAL/PEAK] indicator of STEREO
INPUT 1 L/R to 4A L/R
• Confirm that the [SIGNAL/PEAK] indicator of
corresponding channel lights RED.
• Input the 1 kHz, +12.2 dBu sine wave
to the channel to be checked.
6
Signal level and [SIGNAL/PEAK] indi-
cator of MONO INPUT 1 to 6
(PAD OFF)
•
•
•
Confirm that the output voltage at OUTPUT 1 L to
OUTPUT 4 is +4 dBu ±2 dB.
Confirm that the output level difference between
each OUTPUT is within 1.5 dB.
Confirm that the [SIGNAL/PEAK] indicator of the
corresponding channel lights GREEN.
•
•
All [PAD] switches: OFF.
Input the 1 kHz, -74 dBu sine wave
to the channel to be checked.
